Participatory budgeting (PB) is a mechanism of local government, which brings local communities closer to the decision-making process around the public budget. It is a flexible process, which has been implemented in varying forms across cities of all sizes, within Brazil and beyond. It works to enhance participation in local democracy whilst improving community cohesion and ensuring the delivery of cost-effective local services.

The International Project for a Participatory Society (IPPS) is a group of activists, writers, media producers, and others committed to the basic principles and values of solidarity, diversity, equity, self management.
